Ripl allows uploading a custom logo for each of your brands. If you choose not to upload at that time, you can update your logo anytime by selecting your Brand settings tab under My posts on the mobile app OR under My brand on the web app. You can also update your logo on a post-by-post basis by tapping the logo on the Customize screen.
Under Brand settings and My brand, there is also a toggle switch to display or hide your logo in your posts. If you opt to include your custom logo, you can still hide it on an individual post by clicking your logo in that post and following the prompts to hide your logo for that post.
On the mobile app and Ripl for web, you have the option to upload up to 20 logos per business and switch between them at any time. On mobile, you can switch between logos under your Brand settings by tapping on the pencil icon located on your logo. You'll end up on the Logos tab where you can select one of your previously uploaded logos or select Upload New. You can also double-tap the logo on your post, then select Use a different logo. On the web, you can switch between logos under your brand Creative.
